Abstract: Simulated caviar also named as imitation caviar, is defined as salted roe that comes from a fish except sturgeon fish. Fish roe is removed as a by-product from processing plants and doesn’t have a high demand in Sri Lanka at present. It is essential to add value to fish roe which is of low demand at present and enhance the income of fish processing industries and suppliers. Since Bigeye tuna (Thunnus obesus) is one of the most commercially important tuna fishery resources in Sri Lanka, Bigeye tuna was used as the resource species for the present study. Fish roe samples were subjected to “dry salting” method for different treatments with salt (g): fish roe (g) ratios as Treatment 01 - 0.25: 1.00, Treatment 02 - 0.50: 1.00 and Treatment 03 - 0.75: 1.00. Most appropriate treatment was assessed using sensory evaluation, proximate analysis, pH test and microbiological analysis. Highest average ash content (6.95 % ± 0.06) and maximum lipid content (11.89 % ± 0.88) were recorded for Treatment 03, while greatest protein value (25.65 % ± 0.11) was indicated by Treatment 01. Initial average pH values of the 03 treatments varied between 6.00 - 6.39 with significant difference for all 03 treatments. Treatment 03 (0.75 salt: 1.00 fish roe) has recorded lowest Total Plate Count (TPC) value for a period of 02 months with significant difference for all treatments (P < 0.05).
